Spanish term (edited): 205 caberίas

I am sure that what sounded like "cabería" was in fact "caballería". This is an old unit of land measurement, dating from colonial times still used in Central American countries. Its value varies from one country to another; in Guatamala, according to Wikipedia, it is equivalent to 45 ha 1,266.74 m²:

Expressed another way, this is 45.126674 hectares. If you want that in acres, it's equivalent to 111 acres 22235 ft²:

So these 205 caballerías, in total, would amount to very nearly 9,251 hectares, or some 22,860 acres. (I'll double check all these figures and add a note if I find an error.)

"Caballería" really can't be translated; it's a specifically Hispanic measure. You'll have to keep "205 caballerías" in the translation and add a note.

Confirmation:

Value of caballería in Guatemala: it's reckoned as 45 hectares:

"En Guatemala, el acuerdo gubernativo del 17 de febrero de 1925 estableció que una caballería tiene 45 hectáreas"

(This is from the Google search; the page won't open).

This confirms 45 hectares, and also indicates a much smaller unit, the manzana, which is around 0.7 hectare (7000 square metres):

"…se detectó que 22 terratenientes poseían más de 200
caballerías de terreno cada uno (1 caballería = 45 hectáreas); en
tanto que un promedio de dos millones de jefes de familias
campesinas no poseían ni una sola parcela. Un poco más de un
cuarto de millón eran lo que se podría llamar “pequeños
propietarios”, con menos de 5 manzanas por persona (5
manzanas = 3.49 hectáreas)."

If you do the calculations at 45 hectares, you could round down to 111 acres per caballería, and 205 caballerías will be 9225 hectares or 22795 acreas. Anyway, it's there or thereabouts.
